            This function is used to asynchronously accept a new connection. The
            function call always returns immediately.
          </p>
<p>
            This overload requires that the Protocol template parameter satisfy the
            AcceptableProtocol type requirements.

                  the caller, which must guarantee that it is valid until the handler

                  The handler to be called when the accept operation completes. Copies
                  will be made of the handler as required. The function signature
                  of the handler must be:
</p>
<pre class="programlisting">void handler(
  const asio::error_code&amp; error, // Result of operation.
  typename Protocol::socket peer // On success, the newly accepted socket.
);
</pre>
<p>
                  Regardless of whether the asynchronous operation completes immediately
                  or not, the handler will not be invoked from within this function.
                  Invocation of the handler will be performed in a manner equivalent
                  to using <code class="computeroutput">asio::io_context::post()</code>.
